Be itknown that I, HARRY E. ATWATER, a citizen of the United States of America, and are'sid'ent of Champlain, in the county of 28, secured by part 11.

When the arm 21 is moved into an adjusted position by means of the handle 24, it may be clamped in such'position by means of t "e clamping member 26 in an obvious manner. The freely-revoluble member or annular gear 17 is provided with an actuator or cam said member isadapted to coac t with: the spring member31, having pivoted thereto the contact member 3'2,'Wh1(3h is normally held by meansof' said-spring free from con- 'tact with the member'33, secured to the binding-post 34:. An electric circuit 35- extends from said binding-post 34 to the spring member 31 and has in this circuit a battery bolts 29 to the'stationary vented certain new and useful Improve- Engines, of which the following h a specifica- This invention relates to revoluble electric igniters, and has forits object the production may be accurately timed to assist in the more perfect'operation of the, engine to which it may be attached. Q I The invention consists certain novel features of construction and arrangement. of parts Whl Ch Will be readily understood by reference to the description of the drawings and to the claims, to be hereinafter given.

' Of the' drawings, Figure represents an elevation embodyingthe features of this invention, showing .applied thereto in diagram an electric ignition device; and F ig. 2 represents a vertical section of the-same on line 2 2 on Fig. "1. I,

Similar characters, designate like ,m the direction of the arrow a in Fig.1 will cause a"revolut.ionofthe annular gear memher 17 in the 'o posite-direction,-as indicated -by the arro'w 'm'ember 17 Will cause an electric contact to be madebetween the members 32 33 and arts rawi'ngs.

in the drawings, 10 represents a revoluble quickly broken shaft having abearinginasuitable stationary to properly operate. The member 17 may part 11 The shaft 10 has secured thereto, "be provided with as many projections or 53.0- near one of its ends, by means of a in12, a tuators upon its periphery as may be de spur-gear 13, betwee'n' which and t e collar sired. It is obvious that by mo'vin the arm- 14, secured .to said sha'ftby means of'tlie set- 21 by means of the handle 24' in eith screw 15 ,is interposed the hub lfi'ofan'annution alongthe bracket 28 and clamping the lar gear 17 The hub16 of the annulargearl7 arm in adjusted position the member 17 will be advanced in fI'GlfitiOIl to the gear 13 or moved in the opposite direction, as the case may be, thereby changing the time of-operation of the ignition device to accommodate itself to the operationof the en ine. This makes a very convenient device For regulating the time of operation of'an ignition device, inasmuch as the-mechanism for operating the igniter need not be disconnected and ,may be operated,

10 between the gear 13 and" the collar 14. The extreme outer end of the shaft 12 is provided with another collar 18, secured thereto by means of the set-screw 19, and between this collar and the outer face of the hub of the gear 13 and the collar 18.

The arm 21 has mounted thereon two studs 22,. upon one end of each of which is mounted, so as to be freely revoluble thereon, a pinion 23, the teeth of which mesh with thespungear 13 and the annular gear 17. The upper end of operation of the invention will be thoroughly understood Without any further description.

I claim- 1. In an igniter, the combination or a revoluble shaft, 9. gear secured thereto, a' freelyrevoluble annular gear concentric therewith provided with an; actuator, anignition dethe arm 21 is provided with ahandle 24, by which said arm-may be moved'about the axis of said shaft. The arm 21 near the handle 24 is provided with a bolt extending through a slot 27 in a bracket projection 30, which in the revolution of drawings that two revolutions of the shaft 10.
